I quite like the "component" pointer because it's assigned once at the
start of the function and used consistently throughout.  The other
pointers I complained about were just temporary pointers which meant
different things depending on which line you were on.  They made the
code harder to read.

My only quible is that in the next patch it's called "comp" and here
it's called "component".  Let's just use "comp" for all the local
variables.
